Republicans are seeking a debt ceiling deal that would cut government spending. Zoom in: Biden, who has previously said that he'd consider invoking the 14th Amendment to raise the debt ceiling without an act of Congress, said Sunday that he thinks he has the "authority" to do so. "The question is could it be done and invoked in time that it would not be appealed as a consequence past the date in question," Biden said. Republicans have said they oppose the idea, and any attempt to circumvent the debt ceiling would likely face a lengthy court battle.
